Possibly yes, but then memory accounting would be inconsistent. There
is also a consideration if the reported memory amount should change
when the application switches the display mode. When it comes to
whether this should be version specific I think we should enable this
workaround only for older Windows versions. It's important to note
that these applications aren't expected to work on modern Windows
because GetAvailableVidMem() reports more memory than INT_MAX. It's
just a workaround to make these buggy applications to work in Wine.
